Tailgate Removal
The tailgate can be removed to allow for different
loading situations. Although the tailgate can be removed
without assistance, you may want someone to assist
you with the removal to avoid possible damage to
the vehicle.
To remove the tailgate, do the following:
1. Hold the tailgate up, slightly raised.
2. Release the retaining
cable clip by lifting the
cable so it is level
with the ground and
then push the cable clip
toward the vehicle.
3. Raise the tailgate at a slight upward angle, pull
back on the tailgate at the right edge so it
releases from the block hinge and then move the
tailgate to the right to release the left edge.
Reverse the above procedure to reinstall. Make sure the
tailgate is secure.
